Deuteronomy 25:5-7

Amplified Bible, Classic Edition

⁵ If brothers live together and one of them dies and has no son, his wife shall not be married outside the family to a stranger [an excluded man]. Her husband’s brother shall go in to her and take her as his wife and perform the duty of a husband’s brother to her.

⁶ And the firstborn son shall succeed to the name of the dead brother, that his name may not be blotted out of Israel.

⁷ And if the man does not want to take his brother’s wife, then let his brother’s wife go up to the gate to the elders, and say, My husband’s brother refuses to continue his brother’s name in Israel; he will not perform the duty of my husband’s brother.
